The blood alcohol C2 H; OH level can be determined by titrating a sample of blood plasma with an acidic potassium dichromate solution, resulting in the production of Cr*+ (aq) and carbon dioxide. The reaction can be monitored because the dichromate ion (Cr2 O,²) is orange in solution, and the Cr³* ion is green. The unbalanced redox equation is Cr2 O,2 (aq) + C2H; OH(ag) → Cr³* (ag) + CO2 (g) If 40.35 mL of 0.0711 M potassium dichromate solution is required to titrate 27.5 g of blood plasma, determine the mass percent of alcohol in the blood.

0.9545 g of calcium nitrate salt, Ca (NO3) 2, is weighed, dissolved in concentrated HCl solution and added to 500 ml with water. It is diluted, 100 ml sample taken here is precipitated as CaC2O4, burned in the ash furnace and It is converted to CaCO3 and then to CaO.

Sodium oxalate, Na2C2O4Na2C2O4, in solution is oxidized to CO2(g)CO2(g) by MnO−4MnO4− which is reduced to Mn2+Mn2+. A 50.3 −mL−mL volume of a solution of MnO−4MnO4− is required to titrate a 0.342 −g−g sample of sodium oxalate. This solution of MnO−4MnO4− is then used to analyze uranium-containing samples. A 4.60 −g−g sample of a uranium-containing material requires 33.0 mLmL of the solution for titration. The oxidation of the uranium can be represented by the change UO2+→UO2+2UO2+→UO22+. Part A Calculate the percentage of uranium in the sample.
